Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484276, here are decompositions:

37 + 31484239 = 31484276
67 + 31484209 = 31484276
73 + 31484203 = 31484276
97 + 31484179 = 31484276
349 + 31483927 = 31484276
457 + 31483819 = 31484276
487 + 31483789 = 31484276
613 + 31483663 = 31484276

Showing the first eight; more decompositions exist.
